What bugs did the ancients call dogs?

Tin Sang Lung is a master of making waves, and there is a saying that "dogs look down on people", so in ancient times, dogs were called earthworms.

Dogs were domesticated by early humans from the gray wolf, from 40,000 years ago to 1.5 million years ago. Known as "the most loyal friend of mankind", it is the pet with the highest reproductive rate, and its life span is about 12 to 18 years. In China culture, dogs belong to one of the 12 Zodiacs, ranking 1 1 among the 12 Zodiacs.
